I have experienced a similar problem with specific adidas shoes. I think in 2010 when Djokovic was promoting those purple blue barricades, I bought them and I had this crazy pain in my shins. Never had it before, I thought it was anything else but the shoes. When I switched them, the pain was gone. I realised that some shoes, fit your feet differently, based on how wide your foot is, it can reshape the insole inside, create a disbalance and put more effort on other unstable parts of your body to move your legs... The barricad 7.0 has worked out great for me, looking forward to the 8th.
